[TowerTalk] Lossy traps?

[foxbw at comcast.net]

How “lossy” are traps on a trap tri-bander?   Some manufacturers of non-trapped tri-banders cite the lossy aspect of traps, but how real is that loss?   Can it be measured?   Would someone 500 or 5000 miles away notice the difference between a  trapped tri-bander and a similar tri-bander antenna without traps?  Notice I said tri-bander, not mono-bander, SteppIRs, etc. 

Anyone have any idea?
